Hi,

I guess you have all heard this one a thousand times before but until today,
I thought I knew the difference between the meaning of 'definition' and
'declaration' in C++. Please help me by letting me know which comments are
true and which are not:

// This is a class declaration
class CMyClass;

// This is a class definition
class CMyClass : public CMyBaseClass
{
// This is a member function declaration inside a class definition
void MemberFunction1();

// This is a member function definition inside a class definition
void MemberFunction2() {cout << "Hi";}

// This is a definition
float m_MyFloat;
};

// This is a function declaration
void Function1();

// This is a function definition
void Function2()
{
// This is a definition
int MyInt;

// This is a definition
CMyClass MyClass(4);
}

Many many thanks,
Lucy
